New York: Top seed Dmitry Tursunov eased into the quarter-finals of the Indianapolis Championships, the Russian advancing with a 6-3, 6-3 victory over Marcos Daniel on a day when two leading seeds were upset.
Second seeded Israeli Dudi Sela converted only one seven break points on his way to a 6-4, 7-6 loss to Russian-born qualifier Alex Bogomolov, while American Wayne Odesnik recovered to beat fourth seeded Russian Igor Kunitsyn 2-6, 6-1, 6-1.
Former champion Tursunov`s routine win over Brazil`s Daniel set up a last-eight encounter against familiar foe Frank Dancevic, who advanced with a 6-2, 7-5 over fifth-seeded Benjamin Becker of Germany.
The Russian world number 27 won the Eastbourne grasscourt event last month at Dancevic`s expense and also beat the Canadian in the final here two years ago.
"He`s a shotmaker and I can`t take him for granted," Tursunov told reporters. "In our last few matches I`ve tried to prevent him going for his shots. You have to try to rush him, keep him on the back foot.”
"But I`m sure he`s learned a lot from our previous meetings like I have."
Third seeded American Sam Querrey also booked a spot in the last eight with a 7-5, 6-3 victory over compatriot Rajeev Ram, gaining some revenge over the man who beat him in the Hall of Fame Championships final earlier this month.
